Today we went though a power point that talked more about populations.
Define:
Birth rate-The number of live births per 1,000 population in a given year
fertility rate-how many babies each women is going to have in their lifetime
death rate-number of deaths per 1,000 population in a given year
population growth rate-the rate of how quickly or slowly the population is growing
rate of natural increase-difference of live births and death rate
population density-population per unit area
life expectancy-the expected years of life remaining at a given age
carrying capacity-how many of one species the world can hold given the number of resources
some of the top 10 most populated countries in the world are: China, India, US, Indonesia, Brazil, Pakistan, Nigeria
Some of the top 10 most populated cities in the world are: Tokyo, Japan; Guangzhou, China; Seoul, South Korea; Delhi, India; Mumbai, India; Mexico City, Mexico; New York City, USA; Las Angelis, USA
The world's population is about 7.9 Billion. The US's population is about 300 million. Iowa's population is about 3 million. Harlan's population is about 5 or 6 thousand.
The world's population reached 1 billion in the 1800's. Now a days, it would take about 12 years to gain another billion.
